357-078-540-203

Edgeboard Connectors Overview

The EDAC 357-078-540-203 is a standard card edge connector featuring 78 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch with a 5.08 mm (0.200 inch) row spacing. Designed for vertical panel mount installation, the unit accepts PCBs with a thickness of 1.57 mm (0.062 inch). The contacts are gold-plated copper alloy, rated for 5 A current at an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C, and the housing is constructed from thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual-row female contact design with semi-bellows termination style for secure board engagement
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural integrity within specified thermal limits
• Panel mount orientation supports fixed installation angles for stable mechanical connection

Edgeboard Connectors Applications

• Medical interconnect solutions requiring durable connections
• Agricultural technology equipment operating in harsh environments
• Industrial control systems utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact flange features and bobbin specifications. Ensure compatibility with target PCB thickness and mounting requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through current manufacturer declarations. Validate supply chain availability directly with the manufacturer or certified partners.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 78 positions is required. The 3.96 mm pitch dictates compatible PCB trace layouts. Verify that the application environment remains within the -40°C to +105°C operational range. Consider the panel mount style for fixed installations rather than board-to-board stacking. Ensure the gold plating meets conductivity requirements for the intended signal paths.
